The Bandit 2000A used four 572A tubes in grounded grid. It covered 80–10 meters and required 100 watts drive for 2000 watts PEP input. The amp’s internal power supply operated from 115 or 230 VAC.
The Hunter Bandit 2000B switched to four 572B tubes, and made some changes or the power supply including the addition of a relay and a resistor to reduce idling current. The "B" model power ratings were the same as the "A" model.
The 2000C was a major redesign using a pair of 8163 / 3-400Z tubes, and attendant reworking of the power supply. The "C" model power ratings were the same as the "A" and "B" models.
The 2000C manual was the only one to list full specifications, which may safely be assumed to be nominally the same for all versions.
